This tool does two things;

1. A neural network predicts probable faults in used vehicles based on the vehicle's make, model, mileage and age. The predictions are derived from previous MOT failures for vehicles of a similar condition (MOTs are an annual vehicle test in the UK to assure roadworthiness). You can enter in those details at https://avoidalemon.com

2. (Of limited use outside the UK) The tool provides a visual representation of mileage over time for anybody who has a UK registered vehicle. The odometer reading over time is plotted on a graph which makes it is easier to see inflections which are indicative of changes in usage/ownership. If the vehicle has had the mileage clocked then this would also be more apparent. You can enter any registration at https://avoidalemon.com/car-report .

This is not a replacement for mechanical expertise or even for consulting suitable motoring forums. What I am hoping this tool does is provide a steer on where issues may be present based on previous MOT failures.

For those of you interested in the underlying data, the UK Government has open sourced a lot of data pertaining to vehicles. You can read more about it here - https://dvsa.github.io/mot-history-api-documentation/ , and here - https://developer-portal.driver-vehicle-licensing.api.gov.uk... .

Fair warning should you want to try this yourself – the data, particularly the MOT API, is very messy and required a significant preparation. Mechanics enter data into the national database mostly by freetext and there is little in the way of standardisation. For example, the manufacturer “Peugeot” was spelled in at least 10 different ways and, rather hilariously, the MOT datasheet is occasionally used to insult the vehicle owner - https://www.mirror.co.uk/news/uk-news/two-incredibly-rude-mo...

I'm not so sure. I learned pointers via C++ years before I tackled JS. Though I suspect you mean that the comprehension is similarly difficult, the paradigms are quite different. Visualizing and mentally tracking `this` by scope is aided by the structure of JS (even though it can get hairy with `bind`). Pointers requires a different model of thinking, and it's not one that's native to many languages. I originally came up in the mid-90s with VB3 and it was quite a jump to C++.
Shell has been very open in the last few years that they see themselves as an "energy" company and that they don't care very much if the energy comes from fossil fuels or from renewables, as long as consumers buy it from Shell. They've seen the writing on the wall and are moving to where the money will be in the future. Apart from this acquisition, they have also invested in wind parks (their offshore expertise is quite handy apparently), hydrogen electrolysers for damping renewable production peaks and several other large and capital intensive projects that they are very well positioned to take on.

The main concern seems to be whether they can make the cultural switch in management as there are quite a few "old hands" in middle management that are quite attached to the fossil fuel sector that they grew up with. On the other hand, the CEO and board seem fully on board so we'll see how it plays out. In the coming weeks with the annual report they are expected to present a new strategy document for the coming decade with more details on how they plan to go about it. This is a company that has tens of billions per year to invest in new energy projects, as well as some top tier talent. It'll be interesting to see what they come up with.

Netflix, the streaming service that mainstreamed child sexual exploitation, is now shy of controversy.

From IMDB's content advisory on "Cuties": "Frequent scenes of 11-year-old girls dancing lewdly where the camera pans in and zooms in on the children's buttocks and midsections (both still in skin-tight clothes) Close up shots of the girls dancing with their leg spread above their head while camera focus on crotch area. These views are fairly frequent, but brief."

I never really got the fuss over Twitter, it always felt to me that the only people that cared about what happened on Twitter were other people on Twitter.

Journos seem to love it for some reason so I keep seeing articles on BBC, for example, plagued with random Twitter snippets like having some rando in the article adds something.
I find it somewhat ironic that Twitter has only now banned Trump. They allowed him to stay on his platform so more people would sign-up, follow him and get radicalised. Now he's no longer the President, they've suddenly acquired morality. Fool me once, eh.
And so, we now enter the tumblr phase of Twitter.
Thanks for that, I figured advocating for my privacy is worth at least 50 EUR/yr, so I subscribed.
I wholeheartedly agree. Making automatic alt-text available for those types of posts would go a long way in addressing the accessibility issues that plague image posts on Twitter. Their current UX for adding alt-text is painful and content authors are unlikely to use it... Seems like a great place for automation/OCR
You were specifically trying to cast doubt on Dominion. And now that your statement has been outed as false, you're moving the goalposts to "voting machines in general".
<sigh> I hear you. But Twitter is an incredible service. From the Arab spring to people like @balajis who broke COVID (for me at least) before major news networks.

The only interactive we have as users is positive (a heart or retweet) vs negative (thumbs down on Youtube, downvote on reddit).

I think a broken heart, </3, essentially as a downvote, could do a lot to make Twitter more of a community that rewards and punishes, rather than just allows people to exist in their own eco-chamber. The politicians of the last month would have likely seen way more downvotes / broken hearts than favs and retweets, and that might have done something for them personally...it's at least worth a test if anyone at Twitter reads this :).
I've never seen a Swedish keyboard before. Neat.

On my keyboard I've remapped the caps lock to control, pause/break to suspend, etc. Is "§" used often, or could that be safely remapped?
The way I look at it is that tech frequently has people inventing the same approach over and over. So this actually happens, just it’s not always the version that takes off.

Sometimes I shrug when someone says “I invented Facebook in 1990.” But sometimes that happens, although people don’t normally talk about it in public.

I’ve worked with co-workers who “invented” aspect oriented programming, Jenkins, ajax, nosql sui generis. A few years later in each case I remember thinking “oh yeah this is what John Doe” was building.

So I just chalked this up to people in this company “inventing” mobile computers, dial-up communities, and portals at the same time as compaq, prodigy, and yahoo.

As this is a public reference: GitLab's Postgres cluster handles peaks of 300K tps, where the master node alone supports around 60K-80K. And this is not in-memory (datasize in the order of 8TB, RAM 600GB).

https://about.gitlab.com/blog/2020/09/11/gitlab-pg-upgrade/

And there's still room for vertical scaling.

And if the car camera is blinded by the sun, that raises questions about whether the car could safely pull over to the side of the road. I suppose with advanced simulation the car could perhaps predict glare from the sun and pull over ahead of time (“it’s approaching sundown and we’re driving west, you need to take over in 5 minutes”)
> But I think most importantly the decrease in dev speed and performance is an investment in future scalability.

It makes sense only if you'll ever need this scalability. And you take a hit on other fronts too: Infra cost, Deployment complexity. And both deployment complexity and code complexity also increase QA cost, instability, product and company reputation.

It's resumé-driven development, and it's also entertainment-driven development. Bringing in new technologies gives you a chance to play with a new toy.

Work on your UX, your UI, your idea in general.

I've been working in the recruitment industry for 20+ years and have launched / built / managed a number of large scale job boards and what you currently have isn't enough to make anyone want to post on there.

Recruitment is a chicken and egg game, without candidates (job seekers) you won't sign up advertisers and vice versa. Advertisers are lazy and fickle, they won't waste time and effort putting content (jobs) on your site for no return on investment (applications)

To attract recruiters (advertising on behalf of companies) you will need:

* Integration with third party job posters
* Time and a lot of hand holding
* To offer cheap but not free posting (nobody values anything that's free!)
* To offer them something tey can't do themselves or are too lazy to do themselves such as marketing their jobs for them on social media which raises their brand awareness and application rate.

To attract candidates you will need to offer them something they don't get anywhere else, or do but you do it better / more efficiently with less hassle.

I really wouldn't suggest showing your analytics to anyone, they don't know the context of them for example...

You could have 200 jobs on your site and 200 people that you've targetted specifically for those jobs apply for them each registering a unique hit on your site but those hits generated 200 applications which would not be the same as a spray and pray approach that most other job boards take.

Also get your jobs on Google For Jobs and Indeed - it's a ton of free targetted traffic!
A company isn’t a “citizen”, it isn’t even a “person”.

Also why do we even give credence to ideas such as good corporate “citizenship”? Thank you for not destroying the economy or societal fabric..? Way to be a good for profit entity that probably still isn’t raising wages or helping with the homeless crisis..? There should be strong laws and regulations that bind companies and jail their execs if they step out of line. We shouldn’t depend so heavily on so called good corporate “citizenship”.

I didn’t vote for these executives, their boards, or their investors. This isn’t what democracy looks like.
Right. Act quickly, iterate and improve execution.

Many people have excellent ideas and spend too much time trying to perfect the first moves. Then, if/when they actually begin to execute and something unexpected happens they just abandon the project.

I don't think of anomaly detection as being the end, it's triage. It shouldn't do more than "I found something that doesn't follow the normal patterns, let me page someone to take a look."

This article seems like "it was better back then". Well in my opinion we don't have communities like we used to have with deep trust, even the families are not the same anymore.

On the other hand I am not afraid to go to neighboring city (or when I was a kid it could be even other part of the city) so someone would come up with "hey you are not from around here, what are you looking for a trouble here son?".

We traded deep trust for broad trust. This way price of transactions on bigger scale went down a lot, even if they went up on personal or local level.

In the end broad trust is more useful for people because it enables mobility. One can move to a big city and won't be instantly scammed. If we would value deep trust only, there would be no way for people to move out from "dead end" places.

One could live his whole life in one place and have his deep trust network but that is less and less possible in the current world. That is why we need broad societal trust.

You may have friends at work but yes, don't confuse that with the employer organization itself being your friend. The business will 99.999% do what's better for itself (as defined by the executive team, which is incentivized by the policies of the board) rather that what is best for any employee and sometimes for all employees, though there has to be some agreement with what is best for 'all employees' in order to attract any decent ones.
it's explicitly not free trade, the entire purpose of leaving the EU was to erect barriers to trade and remove the regulation (good and...bad). "free trade" is just a phrase the Tories like to say because "we're the party of protectionism and crony capitalism" sounds bad even if it is honest...if they cared about trade between the UK and the EU then they wouldn't have left the single market or the customs union, but they prioritised ending free movement above absolutely everything else including the UK economy and UK global competitiveness. and after all this, they *still* didn't manage to make the far right of the Tory party banging on about europe.

they were supposed to transcribe all the EU regulations and law into UK law, but they also granted themselves power to change lots of it via regulation (ie without going to parliament)...it's unclear what specifically happened here.

I'm genuinely surprised. The "free speech" route is also the easiest for them: they don't have to make difficult judgments and have an easy reply to any criticism.

I expected that they might be sore in the run-up to January 6, when they were afraid of being blamed for the inevitable. But I assumed that after the inauguration, they'd convince themselves that the threat of violence had faded and they could return to the laissez-faire course.

That's the paradox for them: they want click-generating controversy, but they want it to stop short of real-world violence. Most people are keyboard warriors and it won't spill over into physical action very often -- even demonstrations usually only provoke opportunistic vandalism rather than organized violence.

So I'm surprised that they're continuing to take actions, especially ones that will generate a lot of controversy against them.
Show HN: Growth Hacking Framework for Notion
Undermining is a proactive action to weaken something. Refusing to invest may or may not be undermining depending on prior state and intent (a lack of action with no history can still be proactive, it simply lacks prior state information to assess). Withdraw of investment with clear negative implications is undermining, which is what happened here.

You can weaken through direct attack, withdraw of assistance, or you can even strategically offer assistance to weaken (identify largely unknown harmful processes and help them grow), amongst an array of other strategies, direct and indirect.

The grey area is if you've been a bystander to action and refuse to act one way or another because intent is the only information you have and you can't (fairly) gauge on that alone. This isn't one of those cases, this is a clear case of withdraw of active assistence which undermined CentOS. Business processes often work in reverse of what is explained. It's not likely Red Hat made a decision and then informed CentOS there would be consequences. It's far far more likely Red Hat looked for decisions that had the consequence they desired, chose one, and then informed CentOS that wasn't their intent.

These sorts of games of misdirection of intent and responsibility are played by businesses and sociopaths all the time. Decisions like this are highly strategic and implications are discussed throughly, meanwhile the narrative is crafted to then look benign and non-strategic.
> YMMV

It does, enormously. I've reached out to people via Twitter and had nothing but great experiences. I've had dialogue with people I would never have had access to before. IME, so long as you stick away from politics, Twitter is fine but, of course, this depends on who you follow and interact with.
I find people who stand in disbelief of the markets often don't understand how they are working, and/or why they have and societal value.

Skepticism is healthy, but in this case, it's closer to ignorance.

The ability for corporations to go to the open market to secure capital is contingent upon a high liquidity of buyers and sellers present and actively participating.

The market doesn't exist without "primary" buyers and seller acting on behalf of their company to issue new stock (raising capital) or buying back stocks (returning capital (or via dividends)). Between these two types of transactions, there are participants that are constantly estimating the value of these share. If the price of the share deviates too far from what the company thinks it's worth, it will actually trigger one of those two events.

Options are just another more efficient mechanism to make these estimations on a specific timeframe. They allow traders to have a very specific thesis on what is mispriced and place a trade on it.

Without these trades, the market would lack liquidity, and companies would see an increase in their cost of new capital - which is bad for everyone because it means companies wouldn't invest in growth, equipment purchases, new jobs, etc...
If a bunch of options traders provide liquidity services which the market values at $1m, the market will pay the options traders $1m.

If the options traders decide to armwrestle to decide which of them gets to keep the $1m, the market doesn’t care.

It's not small versus big, Red Hat was a $34B acquisition. It's big and bigger. People are pointing at IBM because this is 100% the predictable consequence of a company like IBM purchasing an open source software organization. Open source isn't in their business model, so of course this was going to happen.
Kubernetes isn't only about scaling. The repeatability of deployment process is a great asset to have as well.
I can assure you that most folks on wall street (speaking about most of the multi-manager hedge funds specifically) have significantly tighter risk limits than anyone on WSB. Frequently drawdowns of even 5-10% can get your sized reduce or get you fired. The YOLO attitude that WSB has is closer to the film "the wolf of wall street" than what actually happens.

While Billions is one of the more realistic shows about finance, it is far from accurate enough to be compared to real life.
Off grid is going to be designed to fit and probably cheap. Not always best. If you panels are near the batteries and near the load what you say can make sense (though I wouldn't be surprised if the charger had a AC step internally, that is clearly optional)

That isn't what you would do for anything tied to the grid. This is far more common (economies of scale mean the parts are cheaper). There you would take advantage of AC's ability to change voltage easily to allow the panels to be farther from the rest of the system. You would also want to use the grid as a backup for any system failures in the solar setup.

Eliminating steps isn't always a good idea.

I agree with you _but_ i don't think CentOS would have survived if not for the redhat acquisition maybe they could have in some alternate way (perhaps rockylinux can achieve this?) but the cost of producing CentOS in that form was way too high if not for the contribution of Redhat,

Unpopular opionion but i think Redhat probably just extended the lifespan of the centos distribution instead of killing it straight away.
